[0023] See also Figure 1 , Figure 1 1 is a schematic diagram of a structure of an embodiment of a network port expansion device for a vehicle provided by the present application. The network port expansion device 100 includes:
[0024] The switch 11 has multiple industrial Ethernet interfaces.
[0025] The switch 11 is a network device for forwarding electrical signals, which can provide an exclusive electrical signal path for any two network nodes connected to the switch. The switch 11 has multiple industrial Ethernet interfaces, each of which has a bridging function and can be connected to a local area network or a high-performance server or workstation.
[0026] The switch 11 has multiple industrial Ethernet interfaces so that it can simultaneously connect multiple debugging devices for debugging, thus avoiding frequent and repeated plugging and unplugging of multiple debugging devices to reduce debugging efficiency. The multi-interface structure of the switch 11 is conducive to improving debugging efficiency.
[0027] The industrial Ethernet interface of the switch 11 is also used to connect a debugging device so as to debug the vehicle through the switch 11 .
[0028] The first T1 conversion box 12 has a first end connected to a domain controller of the vehicle, and a second end connected to a switch 11. The first T1 conversion box 12 is used to convert the vehicle Ethernet interface of the domain controller into an industrial Ethernet interface.
[0029] The first T1 conversion box 12 is a specific electronic conversion device used for interface conversion or signal conversion so as to establish a connection between different devices or systems. T1 represents the digital transmission standard used by the conversion box.
[0030] Optionally, the first T1 conversion box may be an Ethernet interface conversion box or other dedicated interface conversion boxes.
[0031] The in-vehicle Ethernet port is an interface specially designed for internal communication in the vehicle. It is based on Ethernet technology and aims to provide high-speed, stable data transmission and network connection. The in-vehicle Ethernet port is mainly divided into a physical layer interface and a data link layer interface. The physical layer interface type can be 100BASE-T1 or 1000BASE-T1; the data link layer interface involves the format and standard of the Ethernet frame, that is, the protocol for data communication, usually using the ISO / OSI protocol.
[0032] Compared with using other ports for expansion, using the vehicle Ethernet port on the domain controller for port expansion has higher reliability, which is conducive to temporarily adding other devices such as sensors to establish connections with the domain controller during the debugging process, and is also more conducive to unifying the time synchronization mechanism between the debugging equipment and the vehicle into an Ethernet synchronization mechanism. Compared with other time synchronization mechanisms, the industrial Ethernet synchronization mechanism has wider compatibility and applicability, can achieve efficient data transmission, improve the accuracy and stability of data transmission during the debugging process, make data transmission safer and faster, and help improve the efficiency and reliability of vehicle debugging.
[0033] The industrial Ethernet interface is a special interface based on Ethernet technology, used for data communication and transmission in industrial automation and control systems. The industrial Ethernet port type can be RJ-45 interface, SC fiber optic interface or console interface. The industrial Ethernet communication protocol is a series of rules and specifications to ensure data transmission between devices. These protocols ensure the accuracy, real-time and security of data during transmission. Different industrial Ethernet protocols are suitable for different application scenarios and have different performance characteristics.
[0034] Optionally, in the network port expansion device 100 of the present application, the industrial Ethernet port type is an RJ-45 interface.
[0035] The RJ-45 interface is a twisted pair Ethernet interface type used to connect standard Ethernet devices such as industrial computers, IP cameras, and industrial sensors. The RJ-45 interface supports Gigabit Ethernet and 100M Ethernet rates.
[0036] Specifically, the network port bandwidth of the first T1 conversion box 12 is configured to be the same as the network port bandwidth of the domain controller.
[0037] Sometimes, the bandwidth of the network port may not meet the actual usage requirements. At this time, it is necessary to adjust the bandwidth of the vehicle's domain controller to an appropriate size, such as adjusting the 100M bandwidth to the 1G bandwidth. However, at this time, the bandwidth of the first T1 conversion box 12 will not match the bandwidth of the vehicle domain controller, and the rate cannot be increased. Therefore, it is necessary to set the network port bandwidth of the first T1 conversion box 12 to the same size as the vehicle domain controller to meet the bandwidth requirements of the debugging work.
[0038] The first end of the first T1 conversion box 12 is connected to the vehicle Ethernet interface on the vehicle's domain controller, and the second end is connected to the switch 11. The vehicle Ethernet port that is not originally compatible with the switch 11 can be converted into an industrial Ethernet port that can be directly connected to the switch, and the original interface communication protocol is converted into an industrial Ethernet interface communication protocol, so that the data transmission link has the high reliability, real-time performance, high bandwidth and better security of the industrial Ethernet. At the same time, the vehicle domain control end is connected to the switch 11, and the performance of the vehicle can be debugged directly through the debugging equipment on the switch 11.
[0039] The second T1 conversion box 13 has a first end connected to the electronic control unit of the vehicle, and a second end connected to the switch 11. The second T1 conversion box 13 is used to convert the vehicle Ethernet interface of the electronic control unit into an industrial Ethernet interface.
[0040] Optionally, the interface type of the second T1 conversion box may be an Ethernet interface conversion box or other dedicated interface conversion boxes.
[0041] Specifically, the network port bandwidth of the second T1 conversion box is configured to be the same as the network port bandwidth of the electronic control unit.
[0042] When data is transmitted between the second T1 conversion box 13 and the electronic control unit of the vehicle, the bandwidth of the second T1 conversion box 13 needs to be set consistent with the bandwidth of the electronic control unit of the vehicle to ensure the data transmission rate between the switch 11 and the vehicle.
[0043] The second T1 conversion box 13 is connected to the switch 11 at one end and the electronic control unit of the vehicle at the other end, which can convert the vehicle Ethernet port that is not compatible with the switch 11 into an industrial Ethernet port that can be directly connected to the switch, and convert the original interface communication protocol into the industrial Ethernet interface communication protocol, so that the data transmission link has the high reliability, real-time performance, high bandwidth and better security of the industrial Ethernet. At the same time, such a connection relationship is also equivalent to restoring the circuit structure connecting the original electronic control unit of the vehicle to the domain controller, so that the vehicle can work normally to test the vehicle performance.
[0044] See also Figure 2 Optionally, the network port expansion device 100 also includes a debugging converter 14, a first end of the debugging converter 14 is used to connect to the debugging device, a second end of the debugging converter 14 is connected to the switch 11, and the debugging converter 14 is used to convert the non-industrial Ethernet interface of the debugging device into an industrial Ethernet interface.
[0045] Since various types of vehicle debugging equipment commonly used in the market often use different types of connection interfaces, when connecting the debugging equipment to the switch 11, it is necessary to convert the non-industrial Ethernet interface of the debugging equipment to the industrial Ethernet interface used by the switch 11 through the debugging converter 14, and unify the time synchronization mechanism on the external equipment into the Ethernet synchronization mechanism. Compared with other time synchronization mechanisms, the industrial Ethernet synchronization mechanism has wider compatibility and applicability, can achieve efficient data transmission, improve the accuracy and stability of data transmission during the debugging process, make data transmission safer and faster, and is conducive to improving the efficiency and reliability of vehicle debugging.
[0046] Furthermore, the debugging converter 14 includes a CANFD converter, a USB converter, a type-c converter, an OBD converter, a Com converter, and a Dcm converter.
[0047] Specifically, the CANFD converter, USB converter, type-c converter, OBD converter, Com converter, and Dcm converter can convert the CANFD interface, USB interface, type-c interface, OBD interface, Com interface, and Dcm interface into industrial Ethernet interfaces, respectively.
[0048] Through the above-mentioned type of converter, the common debugging device port type on the market can be converted into an industrial Ethernet port to obtain the industrial Ethernet synchronization mechanism.
[0049] After debugging, since the domain controller and the electronic control unit are connected to the switch 11 through the first T1 conversion box 12 and the second T1 conversion box 13, it is only necessary to disconnect the connection ports between the first T1 conversion box 12 and the second T1 conversion box 13 and the vehicle, and reconnect the on-board Ethernet ports of the domain controller and the electronic control unit to restore the original circuit structure of the vehicle. The connection relationship between the two T1 conversion boxes and the switch combination can prevent the original circuit structure of the vehicle from being damaged due to subsequent debugging work, which is beneficial to protecting the original vehicle circuit.
[0050] See also Figure 3 , Figure 3 It is a structural diagram of an embodiment of a debugging device provided in the present application. The debugging device 200 includes a debugging device 21 and the network port expansion device 100 as described above. The debugging device 21 is connected to the industrial Ethernet interface of the switch 11.
[0051] The debugging device 200 uses the internal network port expansion device 100 to achieve debugging of the vehicle without destroying the original vehicle structure, and makes the debugging process efficient and stable.
[0052] Optionally, the debugging device 21 includes at least one of a display, a router device, a radar, a data acquisition device and a remote testing device.
[0053] Providing multiple available device types in the debugging device 21 enables the debugging device 21 to perform more comprehensive debugging of the vehicle.
[0054] See also Figure 4 , Figure 4 It is a structural diagram of an embodiment of a vehicle provided in the present application, wherein the vehicle 300 includes the network port expansion device 100 as described above.
[0055] Different from the prior art, the present application provides a network port expansion device, a debugging device and a vehicle applied to a vehicle, which connects the domain controller through a first T1 conversion box 12 and the electronic control unit through a second T1 conversion box 13, and converts the original on-board Ethernet port on the domain controller end and the on-board Ethernet port on the electronic control unit end in the vehicle circuit into an industrial Ethernet interface with stronger applicability, lower latency, higher reliability and larger transmission volume, and further connects to a switch 11 through the industrial Ethernet interface on the first T1 conversion box 12 and the second T1 conversion box 13 for interface expansion, and at the same time, unifies the time synchronization mechanism of the debugging device and the vehicle connected to the switch 11 into an Ethernet synchronization mechanism with faster speed, higher security, stronger applicability and higher precision, which improves the data transmission speed during the debugging process while protecting the original vehicle circuit, enhances the reliability, security, stability and transmission speed of data transmission during the debugging process, and improves the efficiency of vehicle debugging.
